I don't know why I didn't think of this before, and alot of you guys probly allready know but a hi-lift jack or a.k.a. the farmers jack works really good for breaking loose the beads on atv tires. I had to do this at the dunes to fix a bead leak because of sand between rim and bead. This morning I needed to take some paddle tires off to install regular dirt tires and I used the hydraulic outriggers from my service truck to push down to break the beads, within 10 to15 min. I had both tires done!
